Supercritical Carbon Dioxide Brayton Cycle Turbines Promise Giant Leap in Thermal-to-Electric Conversion Efficiency
Physorg.com
March 4, 2011
Sandia National Laboratories researchers are moving into the demonstration phase of a novel gas turbine system for power generation, with the promise that thermal-to-electric conversion efficiency will be increased to as much as 50 percent — an improvement of 50 percent for nuclear power stations equipped with steam turbines, or a 40 percent improvement for simple gas turbines. The system is also very compact, meaning that capital costs would be relatively low.

Squeezing More Energy Out of Batteries
Technology Review
March 2, 2011
Xerox's Palo Alto Research Center (PARC) has developed a new printing technology that promises to pack more energy into batteries for electric vehicles. By printing a striped pattern of energy storage materials and highly conductive materials, researchers at PARC are making electrodes that are much thicker than those in conventional batteries. These could increase battery storage capacity by 10 to 30 percent while costing little more to manufacture, says Scott Elrod, director of the Hardware Systems Laboratory at PARC. The technology could also apply to metal-air batteries that could store far more energy than anything on the market today.
